Description

Air inlet filter Technical Field The utility model relates to the technical field of air inlet filtration, in particular to an air inlet filter. Background Equipment such as gas turbines and the like which need to be supplemented with air needs to be constantly supplemented with fresh air in operation, and the air in the desert area contains a large amount of sand and dust, and the dust and sand easily influence the operation of the equipment if entering the interior of the equipment. In order to reduce the influence, a multi-stage filtering membrane filtering mode is adopted at present, the filtering membrane can effectively block sand from entering, but sand is easy to adhere to the filtering membrane when the multi-stage filtering membrane filtering mode is applied, so that air entering flux is reduced, and in order to acquire larger flux again, the filtering membrane needs to be replaced, if the filtering membrane is replaced, the filtering cost is definitely increased, the filtering membrane needs to be replaced frequently, and the normal operation of equipment is influenced along with the increase of the replacing frequency of the filtering membrane. Disclosure of utility model The utility model provides an air inlet filter, which solves the defects of the prior art, solves the problem that frequent filtration is needed when sand is blocked by adopting a filtering membrane filtration mode during air inlet, and has stronger practicability. In order to achieve the object of the present utility model, the following techniques are proposed: The utility model provides an air filter, it is ironwork, it includes the rectangle frame, the lower extreme welding of rectangle frame has the lower bolster, a plurality of discharge holes have been seted up to the lower bolster, the lower bolster is provided with a plurality of ripples along its length direction, form the rippled runner between two adjacent ripples, when the air passes through the rippled runner, its rippled structure can block the grit in the air, thereby make the grit in the air discharge from the discharge hole of lower bolster, still need not change when blockking the grit through this kind of mode, thereby reduced filtering cost, and can not cause harmful effects to the operation of equipment. Further, the front side welding of rectangle frame has many crossbars, and a plurality of draw-in grooves have been seted up to the inboard of crossbars, and the front end card of wave folded piece is located in the draw-in groove, can fix the front end of wave folded piece through the crossbars to make wave folded piece remove and lead to wave folded form runner width's increase or shrink because of the flow of air when avoiding intaking, and then cause the influence to the filter effect. Further, the rear side of the rectangular frame is welded with a rear frame body, and the front side of the rear frame body is provided with a fixing frame which acts on the rear side of the corrugated piece to limit the corrugated piece. The corrugated piece can be stably fixed in the rectangular frame through the rear frame body. Further, the lower extreme welding of rectangle frame has the hang plate, and the hang plate is located under the lower bolster, and hang plate convenience stops dropping of grit and discharges to avoid the grit to pile up in the rectangle frame. Further, the rear end of the inclined plate extends out of the rear side of the rectangular frame, the two sides of the inclined plate are bent with side plates, the inclined plate extending out of the rectangular frame is located below the rear frame, the lower end of the rear frame is provided with a plurality of leakage holes, and sand and stone in the rear frame can be prevented from accumulating on the leakage holes along with air flowing backwards. Further, the rear end of the lower backing plate is upwardly bent with a baffle plate, so that sand and stone are prevented from moving backwards in the air flow. Further, the transverse bar is of a concave structure so as to improve the structural strength of the transverse bar, and meanwhile, the limiting effect on the corrugated piece is improved. Further, the wave fold comprises a plurality of V-shaped structures, the openings of two adjacent V-shaped structures are opposite in orientation, and when the airflow passes through the V-shaped structures, the energy of sand is reduced through the surface contacted with air, and the sand is blocked, so that the sand does not have enough power to move forward and drop downwards on the lower backing plate. Further, the V-shaped structure is provided with a plurality of concave structures, and rotational flow is formed when air flows through the concave structures, so that sand and stone movement is blocked. Further, the wave folding piece comprises a first vertical plate, a first inclined plate is bent at the front side of the first vertical plate, an acute angle is formed between the width direction of t
